I have a TZR as well and have collected a light smoke, clear, and dark smoke shield. I love the dark smoke but only for daytime use. The light smoke is a nice compromise b/c it takes the edge off of the sun but can be easily worn at night. I haven't used my clear shield since purchasing the light smoke. I really like the Shark helmets and am going to buy an RSR2 as my next helmet. I really need a helmet with a removable liner b/c I wear a helmet too much now that I don't have a car.
